A CORPORATION OF VALVE.

Application filed June 22,

This invention relates to valves and more particularly to a construction and arrangement of parts tending to simplify, render more efiicient and improve generally devices of this character.

The several objects of this invention as well as the novel details of construction of an embodiment thereof will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure 1 is a sectional elevational view of a valve constructed in accordance with my invention.

Figure 2 is a horizontal sectional view taken substantially on the plane indicated by line 22 of Figure 1, and

Figure 3 is a fragmentary separated detail perspective view of certain of the parts.

Referring now particularly to the drawings wherein like reference characters indicate like parts, it will be noted that there is illustrated a valve having a body consisting of a body proper 10 provided with an inlet 11 and an outlet 12. The body also includes a hub or cap member 13 within which a valve stem 14 is rotatably mounted. The reference character 15 indicates the valve handle.

The valve body is provided with a valve seat 16 with which a valve 17 provided with a disc 18 of suitable material, is adapted to engage. As viewed in Figure 1 the valve 17 is vertically reciprocable toward and away from the valve seat 16 to control the passage of water, steam or the like from inlet opening 11 to outlet opening 12.

For operating the valve 17 I provide a spiral groove 19 formed on the inner wall of the valve body and particularly upon the cap 13 thereof. This spiral groove preferably consists of a pair of superposed continuous spirals. The valve 17 is provided with a stem or extension 20 which carries a spiral element herein shown as consisting of a pair of segmental spirals 21, the ends of which, are spaced to provide spaces or slots 22, preferably at diametrically opposed points. One of the segmental spirals 21 is between or superposed with reference to the other segmen tal spiral so that a double spiral element is provided. While such an arrangement is illustrated it is obvious that a single spiral element will operate with equal efliciency.

Non-rotatably secured to the lower end of valve stem 14 is a yoke member 23 having a 1927. Serial No. 200,673.

to open or close the valve 17 as will be obvious. This form of operating means provides a positive and effective but simple means for'actuating the valve whereupon the same may be positively held in any of its adjusted positions. The construction is -furthermore capable of being economically manufactured with facility and dispatch and quickly and easily assembled.

While one mechanical embodiment of the present invention has been illustrated and described herein somewhat in detail it will be readily apparent to those skilled in this art that various changes in many of the essential and all of the non-essential details may be resorted to without departing from the spirit and scope of this invention and to this end reservation is made to make such changes as may come within the purview of the accompanying claims.

What I claim as my invention is:

1. In a valve structure, a valve body formed witha spiral groove, a valve, a disklike spiral element secured to said valve and provided with slots, and a rotatable yoke engaging said slots for rotating said spiral element through said groove.

2. In a valve structure, a body formed with a spiral groove, a valve, a plurality of segmental spirals secured to said valve with the ends arranged in spaced relation, and a rotatable yoke engaging the spaces between said spiral ends for rotating said spirals 100 through said groove.

3. In a valve structure, a body formed with a spiral groove, a valve, a disk-like spiral element secured to said valve and engaging said groove, a valve stem, and a yoke 105 fixed thereto and slidably engaging said element for rotating the latter through said groove to operate said valve.

4. In a valve structure, a body formed with continuous superposed spiral grooves, a 110 valve, a double spiral element secured to said valve and engaging said grooves, a yoke slidably and non-rotatably engaging said elementand means for rotating said yoke to 0perate said valve.

5. In a valve structure, a body formed with superposed spiral grooves, a valve, a pair of segmental spirals secured to said valve, with the ends thereof arranged in spaced relation, a rotatable valve stem, and means carried thereby and slidably non-rotatably engaging the spaces between said spiral ends for rotating the spirals through said grooves to actuate said valve.

6. In a valve structure, a body formed with a pair of superposed continuous spiral grooves, a valve, a pair of interrupted spirals secured to said valve and engaging said grooves, a rotatable valve stem and a yoke carried by said valve stem and slidably nonrotatably engaging said spirals'for rotating the same through said spirals to operate said valve.

7. In a valve structure, a valve body formed with a spiral groove, a valve, a disklike spiral element secured to said Valve and provided with slots, and means for rotating said spiral element through said groove including a rotatable U-shaped yoke having the leg portions thereof engaged with said slots.

In testimony whereof I a'l'lix my signature.

FRED BRITT.
